" Freg Fassbender United .States Patent O SMOKING PIPES Fred Fassbender, Irvington, NJ., assignor to S. M. Frank (im, Inc., New York, N.Y., a corporation of New Application October 17, 1956, Serial No. 616,452

. 2 Claims. (Cl. 131-225) This invention relates to smoking pipes, and more particularly to means by which the bit of the pipe is detachably coupled or attached to the stem or stummel of the pipe in a manner to insure its correctly aligned position thereon.

One of the obstacles encountered in the manufacture of pipes is the tendency of the bit which, when threadably joined to the stem by conventional methods, often exhibits a tendency to over-turn and thus become disaligned from the stem. A much sought construction is one in which the bit, when threaded home, will be tightly coupled to the stem and at the same time will be correctly aligned therewith. This result is diiicult to secure when the conventional methods are employed to secure the bit to the stem.

It is therefore one of the objects of the present invention to provide a novel means by which the pipe bit can be securely yet removably attached to the stem in a manner to insure correct positioning or alignment of the bit with respect to the stem with the employment of a minimum of parts and effort.

It is another object of the invention to provide a simple and effective means by which the bit can be easily fitted in position and adjusted in relation to the pipe stem or stummel, and to eliminate over-turn or misalignment of the bit.

With these objects, and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,

Fig. 1 is a top plan View of a pipe bit provided with an extension member constructed in accordance with the invention;

Fig. 2 is a side elevational view of the extension member, with the parts thereof in separated relationship;

Fig. 3 is a face view of the friction washer;

Fig. 4 is a sectional view, taken substantially on the line 4--4 of Fig. 2, looking in the direction of the arrows;

Fig. 5 is a longitudinal sectional view through a portion of a bit and pipe stem, showing the same in coupled relation by the use of the improved connection device, and

Fig. 6 is an enlarged longitudinal sectional view through the externally threaded bushing.

Referring to the drawing, 1 indicates a portion of the tubular or hollow stem or stummel of a pipe of conventional construction, and which portion of the pipe integrally or otherwise projects from the bowl in the known manner. Tightly fitted within the end of the hollow stem or stummel 1 is a metallic sleeve indicated at 2. The sleeve usually is provided with a roughened outer surface to maintain it against rotative movement within the stem 1 after it has been ttted therein. This is of known construction. At one end, the sleeve 2 is provided with an external, radially-extending ange 3 ICC which abuts against the end of the stem or stummel when the sleeve is litted therein and against which the forward end of the bit 13 contacts. The sleeve is provided with an internal spiral thread 4 for engagement with the external threads 5 provided on a metallic bushing indicated at 6.

The bushing 6 is provided with a smooth. axial passage 7 (Fig. 6) which enables it to t snugly but rotatively on a shank portion 8 of the bit extension 9. The forward tubular portion of said bit extension is of known form, and includes the tapering part 10 terminating in the hollow, apertured ball 11 at its forward end. The

extension 9 is provided with the usual axial sinoke passage 12 through which the smoke is drawn to pass through the smoke passage 13a provided in the bit 13. Provided on the bit extension 9, at the rear of the tapered part 10 thereon, is an annular shoulder 14 acting as a seat against which a washer 15 is positioned. The washer is of non-metallic nature and may be composed of nylon or of some other material of substantially similar characteristics, and which is slightly compressible and capable of acting as a friction brake against the forward end 20 of the bushing 6. As will be seen in Fig. 5, when the bushing 6 is fitted on the outside of the shank portion 8 of the bit extension 9, the washer 15 will be confined between the forward end 20 of the bushing 6 and the annular shoulder 14. When the bushing 6 is in place as above described, it is confined on the shank portion 8 by being disposed between the washer 15 and the forward end 16 of the bit, and which end 16 may be provided, if desired, with a shallow recess 17 to receive the frusto-conical rear end 18 of the bushing 6.

Provided on the shank portion 8 of the bit extension 9, are threads 19 by which this portion may be threaded into the bore or smoke passage 13 of the stem or stummel 1.

From the foregoing, the construction and operation of the herein-described, bit-attaching means will be readily understood. The nylon or similar washer 15 is tted on the shank portion 8 and is disposed against the annular shoulder 14. The bushing 6 is next tted on the shank 8 behind the washer 15, and the threaded portion 19 of the shank, a part of which protrudes beyond the rear end of the bushing 6, is threaded into the bore or smoke passage 13a of the bit 13. The bushing 6 is thus confined on the shank 8 between the end 16 of the bit and the washer 15 which is clamped between the forward end of the bushing 6 and the shoulder 14. The parts in the relationship above described, are shown in Fig. l.

In the application of the bit to the stem or stummel 1, the spiral thread 5 on the bushing 6 is threadably engaged with the internal threads 4 on the sleeve 2, and the extension and the bushing will rotate together until the bushing is threaded home within the sleeve 2. Further independent turning of the bit and extension 10 can be had and as this occurs, a frictional contact between the forward end of the bushing 6 and the washer 15 takes place so that the bit can turn stiifly in the stem 1, enabling the bit to be thereupon manually adjusted and aligned with the stem, but preventing subsequent inadvertent disalignment.

Having described a single embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is:

l. A pipe comprising, a pipe stem, a sleeve iixedly fitted into one end of the stem, said sleeve being provided with internal threads, a bit having a forward extension member, said extension member having an annular seat positioned within the sleeve', a washer of non-metallic material fitted on said extension member against the annular seat, said washer having a diameter less than the internal diameter of the sleeve and fitting within said sleeve, a bushingftted on the extension member behindithel washer, said bushing being completelyk contined within the sleeve and bit, and being maintained on the extension member by its confinement between the washer and its abutment against the forwardend of the bit, the. forward end of the bit having an annular seat to accommodate one end of the bushing, said bushing being rotative on the extension member independently of the washer :and being provided with anv external thread received by the internal threads in the sleeve.

2. A pipe comprising, a pipe stem, a sleeve xedly fitted into one. end. of the. same, a bushing threadablyy engaged with. the sleeve, a bit having a forward extension,

the bushing being completely confined Within the sleeve and bit, a shoulder on the extension, a washer located within and surrounded by the sleeve, said washer being positioned on the extension between the forward end of the bushing and the shoulder, the bushing being rotative relatively to the extension and being conned thereon between the forward end of the bit and the washer, the forward end of the bit having a tapered seat and one end of the bushing being shaped complementarily to said seat and engaging therewith.
